The reasonable determination of the motor power of the jaw crusher plays a very important role in improving the of the jaw crusher, saving energy and reducing consumption, reducing investment costs, and reducing operating costs. The required power of the jaw crusher is related to factors such as material characteristics, productivity, rotor linear speed and crushing ratio. The following specific analysis of the influence of these factors on the power of the jaw crusher.
1) The impact of material properties on the power of impact crusher: According to the specific power consumption curve of the jaw crusher for different ores, the power consumption of the jaw crusher for different rocks increases with the increase in the circumferential speed of the rotor. Since the jaw crusher can achieve selective crushing, under other conditions unchanged, the physical and mechanical properties of the ore have a impact on energy consumption. 2) The influence of productivity, rotor linear speed and crushing ratio on the power of jaw crusher: The influence of productivity and rotor linear speed on the power of the motor is: the er the productivity, the er the power consumption; the higher the rotational speed of the jaw crusher, The er the power consumption. The circumferential linear velocity of the crusher rotor is the main factor to achieve the material crushing ratio. Therefore, the higher the circumferential speed of the rotor, the er the material crushing ratio, the smaller the product size, and the er the energy consumption.
